This is done to ensure that materials that have been collected for recycling remain available for recycling, so their value is not lost by discarding them to landfill.
Moreover, food and biodegradable materials in landfill sites give off methane – one of the most potent greenhouse gases and one that contributes greatly to global warming. Removing these materials from landfill will reduce emissions equivalent to taking 166,000 cars off Scotland’s roads.
The aim is to gradually remove the key recyclable materials from the mixed waste stream. Mandatory segregation at source, education and - where needed- enforcement will help achieve this over time.
